Computing system with revised notification messages and related methods

ABSTRACT

A computing system may include a server, and a client computing device in communication with the server and operating a local mobile OS. One of the client computing device and the server may be configured to compare a notification message with a database of flagged terms to determine whether the notification message includes a flagged term. If the notification message includes the flagged term and the local mobile OS is in a locked state, the notification message is revised by replacing the flagged term with a placeholder term, and the revised notification message is displayed on a display.

BACKGROUND

Many enterprises (e.g., corporations, partnerships, academic institutions, etc.) maintain enterprise computer networks that allow enterprise users to access enterprise resources, such as hardware and software applications for email, customer relationship management (CRM), document management, enterprise resource planning (ERP), and the like. Also, many enterprises allow users to access the enterprise network via client computing devices, such as smartphones, tablet computers, and the like. In some cases, software applications running on the client computing devices exchange data with the enterprise network, some of which can become saved on the memory hardware (e.g., hard drives, SD cards) of the client computing devices.

A growing trend among businesses is to allow employees to use their personally owned client computing devices both to access company resources and the use and access their personal applications and data. This trend, known as bring your own device (BYOD) or bring your own technology (BYOT), significantly complicates the task of protecting enterprise resources, including confidential and/or sensitive information.

Moreover, the typical client computing device includes some form of a locked state, which can be implemented by the user or remotely by the administrator. Positively placing the client computing device in the locked state typically impairs access to sensitive information. Nevertheless, in recent years, some mobile operating system (OS) providers have provided the option for displaying sensitive information from applications even when the client computing device is in the locked state. In particular, the client computing device may display notifications while in the locked state. Although this feature may conveniently provide some information to the authorized user without necessitating an unlocking step, this same information is also provided to the unauthorized user, and can be problematic for remote administration of sensitive material.

SUMMARY

Generally, a computing system may include at least one server, and a client computing device in communication with the at least one server and operating a local mobile OS. The client computing device may include a display. At least one of the client computing device and the at least one server may be configured to compare at least one notification message with a database of flagged terms to determine whether the at least one notification message includes at least one flagged term. If the at least one notification message includes the at least one flagged term and the local mobile OS is in a locked state, at least one of the client computing device and the at least one server then revises the at least one notification message by replacing the at least one flagged term with at least one placeholder term, and causes displaying of the revised at least one notification message on the display.

Also, the revised at least one notification message may include a portion of at least one notification message and the dummy text. More specifically, the client computing device may be configured to display, on the display, the at least one notification message with the at least one flagged term when the local mobile OS is in an unlocked state. Advantageously, the client computing device may provide easy and secure access to the notification message without exposing sensitive data.

In some embodiments, the client computing device may be configured to execute a source application for generating the at least one notification message, and for determining whether the at least one notification message includes the at least one flagged term. The source application may be for revising the at least one notification message, and forwarding the revised at least one notification message to the local mobile OS.

In other embodiments, the client computing device may be configured to execute a source application for generating the at least one notification message, and forwarding the at least one notification message to the local mobile OS. The local mobile OS may determine whether the at least one notification message includes the at least one flagged term, and revise the at least one notification message.

In yet other embodiments, the client computing device may be configured to execute a wrapped source application for generating the at least one notification message, and execute a mobile device experience (MDX) toolkit software application for wrapping the source application. The MDX toolkit software application may be configured to intercept the at least one notification message from the source application, determine whether the at least one notification message includes the at least one flagged term, revise the at least one notification message, and forward the revised at least one notification message to the local mobile OS.

Moreover, in some embodiments, the at least one server includes an application server, and a push notification server in communication with the application server. The application server may be configured to generate the at least one notification message, determine whether the at least one notification message includes the at least one flagged term, revise the at least one notification message, and forward the revised at least one notification message to the push notification server.

The at least one server may include a virtual desktop application (VDA) server, and a push notification server in communication with the VDA server. The VDA server may be configured to receive at least one notification message, determine whether the at least one notification message includes the at least one flagged term, revise the at least one notification message, and forward the revised at least one notification message to the push notification server. The database of flagged terms may include name values, address values, and date and time values, for example. Also, the at least one placeholder term may include dummy text.

Another aspect is directed to a method including operating at least one server in communication with a client computing device. The client computing device operates a local mobile OS. The method may include operating at least one of the client computing device and the at least one server to compare at least one notification message with a database of flagged terms to determine whether the at least one notification message includes at least one flagged term. If the at least one notification message includes the at least one flagged term and the local mobile OS is in a locked state, then the at least one notification message is revised by replacing the at least one flagged term with at least one placeholder term, and the revised at least one notification message is displayed on the display.

Yet another aspect is directed to a non-transitory computer-readable medium for at least one of a server and a client computing device. The server is in communication with the client computing device, and the client computing device operates a local mobile OS. The non-transitory computer-readable medium has computer-executable instructions for causing the server and the client computing device to perform the above steps.

Referring now to FIGS. 3A-3B and 4 , a computing system 201 illustratively includes a plurality of servers 206 a-206 b, and a client computing device 202 in communication with the plurality of servers and operating a local mobile OS (e.g. iOS, Android, Windows Mobile, Tizen). Of course, the plurality of servers 206 a-206 b is merely exemplary in nature, and other embodiments may consolidate the same functions within a single sever.

As will be appreciated in detail below, the computing system 201 advantageously provides the user of the client computing device 202 with access to a revised notification message 234 even when the local mobile OS is in the locked state, thereby permitting convenient access without required the extra step of unlocking the phone. Further, this ease of access does not come with the cost of disclosure of sensitive information since the at least one flagged term is replaced with non-sensitive data.

The client computing device 202 includes a processor, a memory cooperating with the processor, and a display 230 (e.g. a touchscreen display) cooperating with the processor. In this embodiment, the plurality of servers 206 a-206 b comprises an application server (or web server executing a progressive web application (PWA)) 206 a configured to generate a notification message 233, and a push notification server 206 b configured to push/forward the notification message to the client computing device 202. For illustrative clarity, only one notification message 233 is shown, but in typical use, a large number of notification messages 233 could be processed as disclosed herein.

The application server 206 a is configured to compare the notification message 233 with a database of flagged terms to determine whether the notification message includes at least one flagged term. For example, the database of flagged terms may include name values, address values, and date and time values. Indeed, the database of flagged terms includes any sensitive data as defined by one or more of a given user of the client computing device 202, an administrator of the application server 206 a, or a platform security policy. In this embodiment, the database of flagged terms is stored in the application server 206 a.

The application server 206 a is configured to if the notification message 233 includes the at least one flagged term and the local mobile OS is in a locked state (FIG. 3B), then perform at least the following steps. The steps illustratively include revising the notification message 233 by replacing the at least one flagged term with at least one placeholder term (e.g. the illustrated dummy text in FIG. 3B), i.e. filtering the notification message, and causing the display of the revised notification message 234 on the display 230.

When the local mobile OS of the client computing device 202 is in a locked state, the client computing device can only display the revised notification message 234 in the locked state interface 232. Of course, the client computing device 202 is configured to display, on the display 230, the notification message 233, along with the unlocked state interface 231, with the at least one flagged term when the local mobile OS is in an unlocked state (FIG. 3A). In other words, when in the mobile OS is in the unlocked state, there is no need to filter or revise the at least one flagged term.

In the illustrated embodiment, the push notification server 206 b is in communication (e.g. over the Internet or closed network) with the application server 206 a. The application server 206 a illustratively includes a notification provider module configured to generate the notification message 233, and a filter module 235 configured to receive the notification message. The filter module 235 is configured to determine whether the notification message 233 includes the at least one flagged term, revise the notification message, and forward (e.g. using the Apple Push Notification Service or the Google Cloud Messaging Service) the revised notification message 234 to the push notification server 206 b. The push notification server 206 b is configured to push/forward the revised notification message 234 to the client computing device 202.

In the illustrated embodiment, the push notification server 206 b is optionally configured to push/forward both the notification message 233 and the revised notification message 234 to the client computing device 202 (shown with dashed lines). The client computing device 202 is configured to selectively display the notification message 233 only when the local mobile OS is in the unlocked state, and display the revised notification message 234 when the local mobile OS is in the locked state.

In the illustrated embodiment, the push notification server 206 b is optionally configured to monitor the state of the local mobile OS (shown with dashed lines), and push/forward both the revised notification message 234 to the client computing device 202 when the local mobile OS is in the locked state. The push notification server 206 b is configured to subsequently push/forward the notification message 233 to the client computing device 202 when the local mobile OS is in the unlocked state.

Of course, in other embodiments, the filter module 235 is within the push notification server 206 b. In yet other embodiments, the filter module 235 may not be provided server side and may be provided locally in the client computing device 202 (FIGS. 6-8 ).

Another aspect is directed to a method including operating at least one server 206 a-206 b in communication with a client computing device 202. The client computing device 202 operates a local mobile OS. The method includes at least one of the client computing device 202 and the at least one server 206 a-206 b to compare at least one notification message 233 with a database of flagged terms to determine whether the at least one notification message includes at least one flagged term. If the at least one notification message includes the at least one flagged term and the local mobile OS is in a locked state, then the at least one notification message is revised by replacing the at least one flagged term with at least one placeholder term, and the at least one of the client computing device 202 and the at least one server 206 a-206 b causes display of the revised at least one notification message 234 on the display 230.

Yet another aspect is directed to a non-transitory computer-readable medium for at least one of at least one server 206 a-206 b and a client computing device 202. The at least one server 206 a-206 b is in communication with the client computing device 202, and the client computing device operates a local mobile OS. The non-transitory computer-readable medium has computer-executable instructions for causing the at least one of the at least one server 206 a-206 b and the client computing device 202 to perform steps. The steps include comparing at least one notification message 233 with a database of flagged terms to determine whether the at least one notification message includes at least one flagged term, and if the at least one notification message includes the at least one flagged term and the local mobile OS is in a locked state, then performing revising the at least one notification message by replacing the at least one flagged term with at least one placeholder term, and causing display of the revised at least one notification message 234 on the display 230.

A method comprising: operating an application server, a push notification server in communication with the application server, and a client computing device in communication with the application server and the push notification server, with the client computing device operating a local mobile operating system (OS); and operating the application server to perform at least the following: monitor a lock state of the local mobile OS of the client computing device; generate at least one notification message; comparing the at least one notification message with a database of flagged terms to determine whether the at least one notification message comprises at least one flagged term, the database of flagged terms comprising name values, address values, and date and time values, the database of flagged terms being defined by a respective user of the client computing device and a platform security policy; and only when the at least one notification message comprises the at least one flagged term and the local mobile OS is in a locked state, then performing at least the following: revising the at least one notification message by replacing the at least one flagged term with at least one placeholder term, the at least one placeholder term comprising dummy text, the revised at least one notification message comprising a portion of at least one notification message and the dummy text; forwarding the revised at least one notification message to the push notification server for displaying of the revised at least one notification message on the display; and when the local mobile OS returns to an unlocked state, subsequent to the forwarding of the revised at least one notification message, forward the at least one notification message to the push notification server for displaying on the display, the at least one notification message comprising an original unfiltered notification message; and otherwise, when the at least one notification message does not comprise the at least one flagged term or when the local mobile OS is in the unlocked state, forwarding the at least one notification message to the push notification server for displaying of the at least one notification message on the display, the at least one notification message comprising the original unfiltered notification message.
 8. The method of claim 7 further comprising operating the application server to store the database of flagged terms.
 9. The method of claim 7 further comprising operating the application server to otherwise forward the at least one notification message to the push notification server using a notification service of the local mobile OS.
 10. A non-transitory computer-readable medium for an application server, a push notification server in communication with the application server, and a client computing device in communication with the application server and the push notification server, the client computing device operating a local mobile operating system (OS), the non-transitory computer-readable medium having computer-executable instructions for causing the application server and the push notification server to perform steps comprising: monitoring, via the application server, a lock state of the local mobile OS of the client computing device; generating, via the application server, at least one notification message; comparing, via the application server, the at least one notification message with a database of flagged terms to determine whether the at least one notification message comprises at least one flagged term, the database of flagged terms comprising name values, address values, and date and time values, the database of flagged terms being defined by a respective user of the client computing device and a platform security policy; only when the at least one notification message comprises the at least one flagged term and the local mobile OS is in a locked state, then, via the application server, performing at least the following: revising the at least one notification message by replacing the at least one flagged term with at least one placeholder term, the at least one placeholder term comprising dummy text, the revised at least one notification message comprising a portion of at least one notification message and the dummy text; forwarding the revised at least one notification message to the push notification server for displaying of the revised at least one notification message on the display; and when the local mobile OS returns to an unlocked state, subsequent to the forwarding of the revised at least one notification message, forwarding the at least one notification message to the push notification server for displaying on the display, the at least one notification message comprising an original unfiltered notification message; and otherwise, when the at least one notification message does not comprise the at least one flagged term or when the local mobile OS is in the unlocked state, via the application server, forwarding the at least one notification message to the push notification server for displaying of the at least one notification message on the display, the at least one notification message comprising the original unfiltered notification message.
 11. The non-transitory computer-readable medium of claim 10 wherein the steps further comprises storing, at the application server, the database of flagged terms.
 12. The non-transitory computer-readable medium of claim 10 wherein the steps further comprises forwarding, at the application server, the at least one notification message to the push notification server using a notification service of the local mobile OS.
